Astronomers detect the size of a car asteroid before his strike in the atmosphere



Astronomers in Hawaii discovered the asteroid 2019 MO, nearly 4 meters in diameter, a few hours before entering the Earth's atmosphere and broke down on June 22, about 380 miles south of San Juan, Puerto Rico. Live Science portal.

Media indicates it is The fourth time in history astronomers discover the asteroid so little impact, Previous time has occurred with asteroids 2008 TC3, 2014 AA and 2018 LA, all in the last 11 years.

As the University of Hawaii stated in the statement, its astronomers first demonstrated that UH ATLAS and Pan-STARRS telescopes "can provide enough warning to keep people away from the influence of the incoming asteroid."

The entity explained that the object – the size of the car, though not considered great for the asteroid – was observed four times over a period of 30 minutes in ATLAS facilities in Mauna Loi, on Hawaii, about midnight last Saturday. At that time the object was only 500,000 km away from Earth.

MO 2019 did not cause any damage because it failed to reach the Earth. Despite this, he produced a big flash in the sky, while, according to scientists' estimates, the energy of its influence had to be oscillated between 3 and 5 kilotonnes of TNT, Experts calculate that it traveled at 14.9 kilometers per second.
